Maybe I should just take a deep breath. Out of curiosity, could he stop the divorce the day of it?? I guess that's my dream, not his.
Yes. Take alot of deep breaths. Could he? As far as I know, yes. Don't torture yourself with it though.
If he's coming and hanging out, I see that as a good thing to some extent. If you're not sure if he's flirting, ask. Just text something like "are you flirting with me? ;)"
I know all the spinning that's going on in your head. it's really hard to get a handle on that, or at least it was for me.
Try not to think about his "friend" and it really won't do you any good to tell him anything you know or hear about her. He'll either figure it out for himsoelf or not.
I like the dog idea. I have one (I'm a townie though) and he is an angel.
As far as his b-day goes. By all means get him something from D4 and you could even let her "decorate" a cake for him. As far as you go, the most I would do is a simple card (NO mushy) and maybe a b-day hug. That's just my opinion though.
If you can avoid R talk, I would. It's been over a year and a half since I've gone there with my H and only just did the other day b/c of the sitch.
